Product Description
Low alloy special purpose steels or group L steels contain small quantities of chromium, nickel, vanadium, and molybdenum. O7 and L6 form the group L steels.
TheO7Die Block Steels contain 0.70% carbon with a quenched hardness of about 64 HRC. The alloying elements in these Die Block Steels are chromium and molybdenum, and 1.50% nickel to increase toughness. These Die Block Steel can maintain hardness above 60 HRC for sections of 75 mm (3 in.) thickness.
Chemical Composition(%):
Applications:
1. Diecasting mould(mold, fixed block, upper die, jet nozzle, nitride thimble ).
